根据过滤器逻辑加载更多项目

Question

逻辑在这里..

1. 加载时 div 容器必须根据 li 选择的 id 显示。 Li ID & div ID 必须匹配并显示。其他将被隐藏。

2. 在初始加载时，它必须只显示 3 个项目（在过滤后的基于 ID 之后）。点击“加载更多”链接..它必须在每次点击时再显示 6 个。必须维护基于 ID 的过滤器。

提前感谢您的帮助！

HTML：

<ul>
  <li class="slist selected" id="ele1"><a href="javascript:;">Element 1</a></li>
  <li class="slist" id="ele2"><a href="javascript:;">Element 2</a></li>
</ul>


<div class="cwrapper">
  <div class="contentEle">
    <div class="content ele1">
     Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ve...
    </div>
    <div class="content ele2">
     Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ve...
    </div>
  </div>
  <a href="javascript:;" class="load-more">Load more</a>
</div>

JS：

$('.slist').each(function () {
if($(this).hasClass('selected')) {
$('.cwrapper .contentEle > div.content').hide();
var $postDiv = $('.' + $(this).attr('id')).size();
    var $divEle = 3;
    $('.' + $(this).attr('id'):lt('+$divEle+')).fadeIn(600);
    $('div.content:lt('+$divEle+')').show();

    $('.load-more').click(function () {
      $divEle = ($divEle + 6 <= $postDiv) ? $divEle + 6 : $postDiv;
      $('.cwrapper .contentEle > div.content:lt('+$divEle+')').show();
    });    
 }
});

你可以使用一个简单的过滤器，比如

jQuery(function($) {
  var $els = $('.contentEle .content').hide(),
    $curr;

  $('.slist').on('click', function() {
    var $this = $(this);
    $this.addClass('selected');
    $curr = $els.filter('.' + this.id).hide();
    $curr.slice(0, 3).show();
    $els.not($curr).hide();
  }).filter('.selected').click();

  $('.load-more').click(function() {
    $curr.filter(':hidden').slice(0, 6).show();
  });
});
